Agilent Duraguard Capillary GC Columns
By Agilent Technologies
Columns with built-in guard columns, no press-fit connectors, Duraguard columns minimize front-end contamination and increase column lifetime. They aid in focusing sample onto the front of the column for better peak shape and minimize MSD contamination originating from the column. The DRGD length is 10m for all columns except the DB-624 column cat.no. 92-125-1334G5, which has a DRGD length of 5m.
